Description

Technical Field

[0001] The utility model relates to the field of chain plate machine preparation, in particular to a chain plate machine wing guard welding tool. Background Art

[0002] The chain feeder is composed of multiple chain plates stacked in a fish scale structure to form a complete ring, which requires high welding precision for each chain plate, otherwise the feeder will easily get stuck; the existing chain conveyor includes a transmission chain plate body and wings (guardrails) arranged on both sides of the upper end of the body. The chain conveyor wing structure mostly adopts a grid-type guardrail (as shown in the prior art CN201610564903.1). The structure is generally divided into a horizontal bar, a vertical bar and a fixed plate. The horizontal bar is often also called a main pipe, and the vertical bar can also be called a riser, which is used to support the main pipe. The fixed plate is connected to the lower end of the vertical bar for fixation. Generally, the metal guardrail is fixed by a tooling fixture on the welding table, and then the metal guardrail is welded by manually driving the welding gun.

[0003] The prior art CN201821745251.2 discloses a welding fixture for a guardrail, comprising a base, a positioning block, and a clamping device, wherein the clamping device is fixedly provided on the upper surface of the base, the clamping device is in a rectangular layout, positioning blocks are fixedly provided at both ends of the upper surface of the base and are in the same horizontal line as the clamping device, and a limiting device is fixedly provided at the center of the base. Although the utility model can quickly clamp and weld the grid-type guardrail, the following problems still exist:

[0004] 1. The utility model can only weld grid-type guardrails, and it is difficult to weld guardrails of other shapes.

[0005] 2. In the existing guard wing, there is a guardrail composed of a cross bar and a plurality of connecting elbows (such as Figure 1 As shown in the figure, the bent pipe array is arranged on the cross bar, and the fixed plate is arranged at the end of the bent pipe. The bent pipe is used to enable the guardrail to be arranged on both sides of the main body. However, the bent pipe is easily deflected during welding, resulting in the fixed plate being unable to fully fit with the side of the chain plate machine body during installation, affecting the product quality. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a chain plate machine wing guard welding tool, which uses the vertical support part and the horizontal support plate of the limit device to accurately position and fix different parts of the bent pipe to prevent it from deflecting during welding and improve product quality.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] Provided is a chain conveyor wing welding tool, comprising: a base, a limiting device; the limiting device is arranged on the base at intervals and can limit and fix the bent pipe;

[0012] It should be noted that the position of the limit mechanism can be adjusted through the adjustment mechanism, so that it can position and fix the bent pipes with wings of different sizes, which not only improves the applicability of the tooling, but also makes the welding process more efficient and convenient.

[0013] Preferably, the adjustment mechanism is positioning holes arranged at intervals on the base, and the positioning seat is fixed on the base through the cooperation of the screw and the positioning hole.

[0014] It should be noted that, through the cooperation between the screw rod and the positioning hole, the position of the positioning seat can be accurately fixed, thereby ensuring that the limiting device accurately limits the bent pipe.

[0015] Preferably, the adjustment mechanism comprises a slide rail and a slider, the slide rail is arranged on the base, the slider cooperates with the slide rail and can slide along the slide rail, and the positioning seat is fixedly connected to the slider.

[0016] It should be noted that the combination of the slide rail and the slider allows the limit device to move smoothly on the base, which not only improves the convenience of adjustment, but also helps to reduce errors that may occur during the adjustment process, further improving the welding quality.

[0020] It should be noted that the upper end of the bent pipe is supported by the first support plate and the second support plate, so that the bent pipe connected to the vertical support part can remain horizontal and prevent the upper end of the bent pipe from being pressed downward under the action of gravity, so that the bent pipe connected to the horizontal support plate can fit tightly with the slot and prevent the lower end from warping outward and affecting the welding accuracy. The various components of the limit device are welded and strengthened by setting a reinforcing plate to prevent them from deformation and ensure welding accuracy.

[0021] Preferably, a limiting plate capable of limiting the wing fixing block is provided at an upper end of one side of the first supporting plate away from the second supporting plate, and a limiting groove capable of clamping the fixing block is provided on the limiting plate.

[0022] It should be noted that the fixing blocks of the wing guards are limited and fixed by setting limiting plates so that they can be on the same plane, so as to ensure that the wing guards can be accurately fitted and fixed to the chain conveyor during installation, thereby improving product quality.

[0023] Preferably, the inner wall of the card slot is provided with anti-slip grooves or rubber pads.

[0024] It should be noted that the anti-slip pattern or rubber pad design on the inner wall of the slot increases the friction between the slot and the elbow, effectively preventing possible sliding during welding and improving the welding accuracy of the product. In addition, the rubber pad can effectively reduce the wear between the elbow and the slot, thereby extending the service life of the tooling.
